A near-future society where the war between vampires and humans has come to an end.
However, the 'Hunter Family,' who have hunted vampires since ancient times, still despises them.

'Vane Hunt' was adopted into the Hunter family after his unique constitution caught their attention.
Having worked for the family his entire life without ever being acknowledged as a true member, he is now given a new mission:

To approach 'Theodore Vasilescu,' the sole survivor of the high-ranking vampire 'Vasilescu Family.'
Vane's father orders him to steal the Vasilescu family's heirloom by any means necessary.

By utilizing his unique constitution—one that prevents him from becoming addicted even if his blood is sucked by a vampire. In other words, by using his body.
